The present 'invention relates to lining anchors, such as are used in connection with a refractory lining applied to furnaces, and more particularly to a shield intended to be relative movement of the various parts thereof will be permitted after the lining has become set and vitriiied. i

In applying a refractory lining to furnaces in plastic condition it is necessary to provide anchoring means for securing the lining to the furnace wall. Since the lining expands and contracts to a much greater extent than the wall, in the use ofthe furnace, it is desirable :i115 thatthe anchoring means be such as to permit such expansion and contraction of the lining independently of the wall, 'so as to avoid subjecting both the lining and the wall to undesirable stresses and resulting injury. The

" anchoring means is usually applied as the lining is constructed, and the refractory material, which is in a stiff plastic condition, is beaten or pounded about suoli means. It is, therefore, necessary during the construction -4a5 of the lining to provide some means whereby the plastic material will be prevented from entering in between the parts of the anchoring means and prevent relative movement thereof. My invention is directed to a shield adapted to be mounted upon the anchor, in a manner hereinafter described, so as to permit relative movement between the variousV parts thereof, and it is the principal object of the invention to provide a shield that can be economically 5 produced and conveniently handled and installed. Further objects and advantages of the invention will appear from the following detailed description when taken in connection 40 with the accompanying drawing which illustrates one embodiment thereof, and. 'in

which Figure 1 is a front -elevational view of the shield of my present invention showing it in 45 position upon an anchor;

Figure 2 is a fragmentary sectional view taken along the line 2-2 of Figure 1, through a furnace wall and lining having anchoring means appliedv thereto, and illustrating the `50 application of my shield;

Figure i8 is a front elevational view of the shield; and

Figure 1 is a side elevational View of the `shield partly in section. 5 used in lconnection with such anchors whereby wall 11. The other member 12 comprises ja base 13 `having ya relatively long upturned arm 14, and a relatively short upturned arm 15. Aslot 16,- of sufficient width to accommo-y date easily the arm 8 of the tief?, is formed in base `13 adjacent arm 15 by stamping out a lip 1 7 from'the base. In 'applying membe'rf' toV member 12, it is simply slipped over the arm 8 which` extends upwardly through the 'slot 16.v The slot 16 is longer'than the width of arm. 8 of member '6, as shown in Figure 1,V

andl this difference permits translatory movement between members' and'12. The anchor members are thus connected so as'fto have relative movement both vertically and'h-orizon- 'tally so vthat expansion and contraction ofthe lining may takeplace in all directions in the plane thereof independently ofthe wall thus Aavoiding setting upjundesirable stresses in either the wall or the'lining.

As will be seen from Figure 2, the member 6 is placed about one of the bricks 1 0 in the retaining wall 11 and is anchored between two courses of bricks as by embedding itin the mortar 18 betweenthe courses. The dimensions of member 6 are such that arm 8 lwill project inwardly beyondthe wall yto en `gage member 12; vTo assure play Yat the connection between the anchor members 6 and 12, and to preventthe plastic lining material from lbeing beaten into the slot 1G during the process of building the wall, I provide a. shield 2O adapted to be Vplaced about the joint or connection between the anchor members, plastic lining being then built around this shield.

The shield 20 comprises a metal plate of a height to extend above the anchor, as shown in Figure 2, and of a width greater than the width of the member 12 of the anchor, so that it will extend therebeyond, as shown in Figure 1. This shield may be stamped from sheet` metal of suitable gauge, and may be either preformed to the shape shown in Figure 2, or it may be formed to this shape by the pressure of the plastic material pounded upon it. A longitudinally extending slot 21 is provided 'in the lower portionof the shield 20 whereby the shield may be slipped over member 12 of the anchor until it abuts the downturned lip 17 thereof. `Said slot is of such height and width as to readily slip over the arm lll and base 13 of member 12 of the anchor', and to permit relative movement of said anchor members, while being sufficiently restricted to prevent entry of plastic material between or about the anchor member to a suiiicient extent to interfere with relative movement therebetween. A flange 22 is formed in the bottom portion of the shield 2O for a purpose which will be hereinafter described.

In practice, the anchor member 6 is applied to the furnace wall as above described and the plastic material is built up to said anchor part in the usual manner. The anchor member 12 is then connected to member 6, and the shield 20 is slipped over member 12 until it abuts the downturned lip 17 and with the flange 22 thereof curved about the base portion 7 of member 6. The plastic material is then pounded in upon the anchor. It will be noted that the upper part of the shield rests against a portion of the retaining wall 11 and the shield therefor forms` in effect, a pocket 24 in the lining surrounding the connection between members 6 and 12 of the anchoring means and e'ectually prevents access of the plastic material about or between arm 8 and the transverse slot 16. It will thus be seen, that after the wall has become set and vitrified, the connection between the arms of the lining anchoring members will be lfree for relative movement both vertically and horizontally, and the lining is capable of eXpansion and contraction independently of the wall and in all directions in a plane parallel to the wall.

What I claim is 1. In combination, a retaining wall, a refractory lining, an anchor member embedded in said wall, an anchor member embedded in said lining. a connection between said members at a point outside the plane Vof said retaining wall permitting expansion and contraction of the lining in every direction in the plane thereof independently of the retaining wall, and a shield having a slot therein accommodating one of said members and cooperating with said retaining wall and the other of said members for encasing said joint,

2. In combination, a retaining wall, a refractory lining, an anchor member embedded in said wall, an anchor member embedded in said lining, a connection between said members at a point outside the plane of said retaining wall permitting expansion and contraction of the lining in every direction in the plane thereof independently of the retaining wall, and means associated with one of said members and cooperating with the other of said members to form a pocket about said joint.

3. In combination, a retaining wall, a refractory lining, an anchor member embedded in said wall, an anchor member embedded in said lining, a connection between said members at a point outside the plane of said retainingl wall permitting' expansion and contraction of said lining in every direction in the plane thereof independently of the retaining wall, and a shield associated with one of said members, said shield having` a flange at one end cooperating with the other of said members, the shield guarding said connection.

l. In combination, a retaining wall, a re-y fractory lining at the inner face of the wall an anchor member secured to the wall and projecting inwardly beyond the inner face thereof, an anchor member secured to the lining, a connection between the 'outer endA of the lining anchor member and the inner end of the wall anchor member permitting expansion and contraction of the lining in all directions in the plane thereof and independently of the wall` and a shield of sheet material contacting at its upper edge the inner face of the wall and extending downwardly and inwardly from the wall and about the connection, said shield and the wall forming an unobstructed space enclosing said connection.

5. In combination, a retaining wall, a refractory lining at the inner face of the wall, -an anchor member secured to the wall and projecting beyond the inner face thereof, an anchor member secured to the lining, a connection between the outer end of the lining anchor member and the inner end of the wall anchor member permitting expansion and contraction of the lining in all directions in the plane thereof and independently of the wall, and a shield member contacting the inner face of said wall and projecting inwardly therefrom and forming with the inner face of the wall an unobstructed space enclosing said connection.

6. In combination, a retaining wall, a refractory lining at the inner face of the wall, an anchor member secured to the Wall and projecting inwardly beyond the inner face thereof, an anchor member secured to the lining, a connection between the outer end of the lining anchor member' and the inner end of the wall anchor member permitting expansion and contractionof the lining in all directions in the plane thereof and independently of the Wall, and a shield member inclined downwardly and inwardly from the wall with its lower portion extending beneath the inner end of said Wall anchor ineinber, said shield forming with the inner face of said Wall an unobstructed space enclosing said connection.

In Witness whereof, I hereunto subscribe my neme this 29 day of July, 1930.
